Seabirds are heavily threatened by anthropogenic activities, and their conservation status is deteriorating rapidly. Nonetheless, these pressures are unlikely to impact all species uniformly. It remains an open question whether seabirds with similar ecological roles are responding similarly to human pressures. Our aims were as follows: (a) to test whether threatened versus non‐threatened seabirds are separated in trait space; (b) to quantify the similarity of species' roles (redundancy) per IUCN Red List Category; and (c) to identify traits that render species vulnerable to anthropogenic threats.

海鸟的生物学特性预测灭绝风险和对人为威胁的脆弱性

海鸟受到人为活动的严重威胁，其保护状况正在迅速恶化。尽管如此，这些压力不太可能对所有物种产生均一的影响。生态角色相似的海鸟对人类压力的响应是否同样是一个悬而未决的问题。我们的目标如下：（a）测试在特征空间中受威胁的和未受威胁的海鸟是否分开；（b）量化每个自然保护联盟红色名录类别中物种角色（冗余）的相似性；（c）确定使物种易受人为威胁的特征。
